Yes GDB has a lot of code dealing with xSYM support, but it's not
functional in the original Apple version.
My modification includes:
- Added CW9's xSYM format (3.3.3R0) to bfd.
- Added automatic loading of .xSYM files for CFM fragments when gdb
founds it in the GDB_CFM_XSYM_PATH directory.
For exact changes please do a cvs diff.
